To all whom t may concern:

Beit known thatLALBERrBIsHoP CHANGE, a citizen of the United States,residing at Centralia, in the county of Boone and State of Missouri,have Iinvented certain new and useful Improvements in Transfer-Boardsfor Telephone or Telegraph Circuits; and I do de-- clare the followingto be a full, clear, and exactdescription of the invention, such as willenable others skilled in the art lto which it appertainsjto make andusethe same.

Thisinvention relates to an improved transf er-board for telephone andtelegraph circuits.

In the ordinary form of transfer-board the transfer of any one wire fromone connection to another is made bybridging over from one connection toanother with a piece of wire.

The object ofthe present invention is to obviate this crude andobjectionable practice and to provide means whereby the transfer fromone connection to another may be easily and speedily effected.

With this and other objects in vview the invention consists of certainnovel' features of construction, combination,and arrangement of `parts,as will be hereinafter more fully described, and particularly pointedout in the appended claims.

In the accompanying drawings, Figure 1 is a front elevation of ajunction-box embodying my invention. Fig. 2 is a rear elevation thereof.Fig. 3 is a vertical central section, and Fig. 4 isa detail view of thecross connecting-board on an enlarged scale.

Referring now more particularly to the drawings,the numeral l representsajunctionbox of any approved form and construction, which maybe providedat the front and rear with hinged doors 3 and t for convenience ingaining access to the parts inclosed therein.

5 is a tube which is employed in the present instance for inclosing theadjacent ends of the two cables 6 and 7, one of which is the line-cableand the other a cable leadiugfrom a switch-box (not shown) in theordinary manner, which cables extend through the tubes into thejunction-box.

Inclosed Within the junction box 0r casing are the transfer-board S andfuse-board 9, to which the wires and circuit. connections are attachedinanypreferred manner. The mode of connecting up the parts in the circuitforms no part of this invention, and henceis not specifically shown.

The line-wires are attached to suitable connections on thetransfer-board 8, the said connections consisting in the presentinstance of jacks or sockets l0. These jacks in accordancewith myinvention are arranged in one or more rows in a circle or a segment of acircle concentric with an opening 1l in the board, through which theinsulated switch or transfer wires 12,1eading from the fuse-board,extend. The free ends of these Wires are provided with spring-plugs,pins, or other suitable connections 13 for engagement with the socketsor jacks l0. Each jack and springplugis suitably numbered, lettered, ornamed, according to the line orV drop connected to same. I may, ifdesired, mount the plugs upon the switch-board and the jacks upon theends of the wires or use any other suitable form of connecting means.

From the foregoing description, taken in connection with theaccompanying drawings, it will be seen that the jacks of each row areequidistant from the central opening 11 and that the switch or transferwires 12 are of the same or approximately the saine length and radiatefrom a common center, thus adapting either wire to be easily andconveniently connected up with either of the jacks on thetransfer-board. of bridging over from one connectionto another, asis thecommon practice, and renders unnecessary the cutting of any wires. Theadvantages of the invention will thus be readily perceived by thoseconversant with the art.

Having thus described my invention, what I claim as-new, andvdesire tosecure by Letters Patent, isf 'v l. A transfer-board provided with anopening and terminals for wires arranged concentric therewith, combinedwith vtransfer-Wires extending through said opening and provided withmeans for engaging said terminals,\\'he1e by the wires extend radiallyfrom said opening and either wire may be engaged with either of saidterminals at will, substantially as described. Y

2. A transfer-board provided with anopening and a circular row ofterminals concentric This obviates the necessity IOO In testimonywhereof I have hereunto set my hand in presence of two subscribingwitwith the opening, combined with transfer- Wires extending throughsaid opening and provided with means for engaging said ternesses.

lninals, whereby the Wiresxtend radially A. BISHOP CHANCE. from saidopeningand either wire may be en- Witnesses:

gaged with either of said terminals at will, HARRY W. THOMAS,
